UPDATE 10/26: According to the National Hurricane Center, Hurricane Sandy is still on course to hit the East Coast of the United States on Tuesday morning. The huge storm is being called Frankenstorm as it is expected to arrive the day before Halloween and will be boosted by a full moon.

Although Sandy is a hurricane now, it will probably be downgraded to a tropical storm when it arrives. However, its massive size, the moon's pull, and its slow pace may cause severe damage - predicted at around $1 billion - in the heavily populated region. Rainfall and high tides preceding its arrival should begin on Sunday. Major cities such as New York, Philadelphia and Washington, D.C. appear to be in the storm's path. Sandy currently has a diameter of 1,500 miles and is moving at a slow pace of 16 miles per hour (more damage). Right now tropical winds extend 150 miles from its center. As with any storm, its path and strengh could change.
